  • Patent number: 11503552
    Abstract: A wireless device that indicates multiple power classes to a network node, a network node that uses the indicated multiple power classes, and related methods of operation for the wireless device and the network node are disclosed. The disclosed embodiments aim at an increase flexibility in setting different power classes in different communication scenarios while reducing signalling overhead for capability signalling for the wireless device. This is achieved by using at least one set of power classes defining at least two power classes of the wireless device. Each set of power classes applies to a transmission band (A, B, C) supported by the wireless device and each power class in each set of power classes applies to a specific operative condition of the wireless device.
